UNITED STATES PATENT QEEIGE0 JESSE P. FULGHUM, OF MILTON, INDIANA, ASSIGNOR OF ONE-HALF HIS RIGHT TO HOOSIER DRILL COMPANY, OF SAME PLAGE.

IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 156,150, dated October 20, 1874; application filed August 5, 1874.

To all whom it may concern:

Beit known that 1, JEssE P. FULGHUM, of Milton, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Seeding Mechanism for Grain-Drills, of which the following is a specication:

This invention relates to that class of drills in which a vertical distributing-wheel, having a carrying-flange, rotates within a secondary hopper; and consists in providing mechanism for regulating the quantity of grain to be dropped without changing the speed of the rotating-wheel, as hereinafter more fully described.

Figure 1 is a perspective view of a secondary hopper embodying my invention. Fig. 2 is a vertical section at the side of the gagedisk, and Fig. 3 is a vertical section of the same in the plane of the feed-shaft.

A represents a seed-cup, having a flange, B, for securing it to the bottom of the main grain-hopper, and an aperture, O, for receiving the grain from a corresponding aperture in the bottom of the main grain-hopper. This seed-cup, in its general features, may be made similar to any of the well-known casings for flanged rotating side-delivery distributingwheels.

The vertical seed-distributing wheel D may also be made in any of the improved forms now in use, though a preferred type is here shown, having a iiat vertical disk at one side with a hub, d, journaling in the casing, and a ribbed grain-carrying ange, as shown.

E represents a thin at vertical disk, made to it loosely the inside of the carrying-ange of the distributing-wheel D, and having a hub, F. The hubs d and F are each pierced with non-circular apertures, the former being loose on the feed-shaft Q, while the latter is rigidly attached by a screw or pin, h. I represents a guard-plate, traversing the `channel in the upper rear end of the casing close to the disk E, and allowing the carrying-ange to revolve around it snugly. This guard-plate is provided with an eccentric collar, which surrounds the hub F and serves to gage the grain-channel without diminishing the capacity of the seed-cup. The circular opening in the collar fits loosely around the hub, so as to allow the hub to revolve Within it.

The pin h may be allowed to project, as shown, so as to hold the collar and guardplate in place, or a separate pin or other suitable means for preventing lateral movement of the collar on the hub may be employed.

The converging side of the casting of the seed-cup is provided with a slot inclining from the seed-shaft upward and rearward to correspond with the inclination which may be desired to give to the guard-plate, and within this slot the guard-plate is adapted to move laterally and simultaneously with the gagedisk E.

The gage-disk and guard-plate are on the feed-shaft, and move laterally with the same. It is by an end movement of this shaft that the dropping capacity of the distributer is regulated, although I have not deemed it necessary to show the mechanism by which the same is accomplished, as I have fully described mechanism for a similar purpose in Letters Patent No. 145,795, granted to lne August 23, 1873, which mechanism or any other appropriate means may be employed.4

The seed-wheel D and gage-disk E rotate in unison, and when it is desired to work the drill to its greatest capacity the seed-shaft Q, is slid endwise, so as to force the disk E closely against the back of the wheel D, which sliding causes a corresponding movement-of the guard-plate I.

When it is desired to drop any less quantity, or to diminish the carrying capacity of the ange on wheel D, the seed-shaft is moved in an opposite direction, which advances the gagedisk and guard-plate, and thereby diminishes the quantity of grain which the Wheel or flan ge is capable of delivering.

The play of the seed-shaft should correspond with the width of the iiange on seed-wheel, and any place within this limit may the seeding capacity of the device be regulated at will without any change ot' speed or gearing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the vertical gage-disk E, the guard-plete I, provided with a collar which acts as a bearing for the hub of said disk, and slides laterally with it on the same sha-ft; through a, slot in the easing of the distributer, substantially as shown and described.

2. In the secondary hopper of a. graimdrill, the eccentric, collar described, whereby the seedchalnnel is gaged Without diminishing the carrying capacity oi' the seed-cup, substantially als shown and described.

In testimony whereof, I have hereunto set my hand this 27 th day of J lily, 1874..
